This invention relates to improvements in sectional box and platform, and more especially to means for stackin box sections on the platform, and one on ti 1 the same in proper alinement.

Our improved device ,can

anddurable-at'relatively low cost and with economy in the use of material.

Other features and advantages of our invention will appear more fully as we proceed with our ap lication. i

In that form 0 device embodying the T6811 tures of our invention shown in the accompanying drawing, Figure 1 is a view in side 16 elevation of a platform with two box sections stacked thereon; Fig. 2 is a top plan view, Fig. 3 is a view in end elevation, and Fig. '4

'is a view taken as indicated by line 4' of Fig. 3.

, As shown in the drawings, 10 indicates in general a raised platform preferably (made out of pressed steel. In the forming of the .platform a substantially rectangular sheetof metal is used, and the side margins bent down-- wardl to form vertical side walls as indicatedy 10. The top of-the platform is indicated by '10. In order-to strengthen the platform, the vertical side walls are provided with vertical corrugations 10, said corrugations referably havlng' their upper ends 7 cennected y horizontal corrugations 10 extending across the top surface of the platform. The corru ations10 and 10 serve to strengthen and stifien the platform, and the corrugations 10 also serve to 00-0 erate with 5 the retaining lugs on the lower ox section to hold ,the same in place, as will be more particularly described herein-after. .A .pluralit of box sections are adapt to be stacke on the form a box or oin o I These sections are. also preferably out of any. desired height. formed In i'g'. ,3, one of these sections is. shown Each box section preferably has, its side walls-- provided with horizontal corrugations. here e other, to hold v be made strong Platform in order to pressed steel,'eachcompris1ng a rectangularframe with four side-walls and" shown as projecting outwardly, as indicated by 11. These corrugations serve to strengthen and stifien the box. sections and also assist in holding the retaining lugs in 1place, as will be described more particularly eremafter.

We shall now describe the retaining lu's used to hold the lower box section on t e platform and the upper-box sections on'the lower, ones. Each box section is provided .with two retaining lugs attached to each side-wall, as indicated by 12. Each of these lugs has itsupper part provided with two or more corrugationslQ, 12*}, fitting nicely over one or more of the lower corrugations 11, 11, of the box section, and the lugis held in place by tworivets 13, 13.' By this construction, the lug may be very*- securely and firmly held in place by' the use of only tworivets. v,T'he corrugations on the lug fit over andrest snugly a ainst the corrugations in the 'box section, t us resisting any. lateral twistin of the lug. Each side lug has a lower epending end, as indicated by 12", which is adapted for. insertion in one of the vertical corrugations 10 in the side wall of the platform. By inserting the lug ends in. these vertical corrugations, platform does not need to be slotted to accommodate them and this permits the box sections to be su 'stantially as long and wide as the latforms, thus increasing the capacity of t e box over those formerly used. 7

Each box section is also provided with'a retaining lug 14 at each end, these lugs being similar to the side lugs 12. Preferably, however, the upper parts of these lugs are made somewhat. longer and provided with four corrugations 14" fitting over the corruga- .tions 11 in the end wall of the box section; We have here shown these'end lugs as fastened to the box sections with three rivets 15. The lower depending end 14: of each end retaining lug is adapted to fit over the end of the top of the V o5 the-platform t assist in holding the lower" I most box section in place on the platform.

Our box sectionmay also be fitted over a lower box section, as shown in Fig. 1, in

which case the depending ends 12? of the side lugs and the depending ends 14) of the end ln s fit over the box section underneath;

Vhile we have. shown and described certain embodiments of our invention, it is to be understood that it is capable of many modifications. Changes, therefore in the construction andarrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims, in which it is our intention to claim all novelty inherent in our invention as broadly as possible in View of the prior art.

What we claim as new, and desire tosecure by Letters Patent, is:

A box having vertical side wallsand a removable bottom, said bottom carrying vertical flanges adapted to space the same from a support, said flanges having vertical corru gations therein, 'and'said side walls having depending members adapted to engage the corrugations in the flanges ofthe bottom to prevent relative horizontal .movement between the side walls and the bottom.

In witness whereof, we have hereunto set our hands this 7th da of November, 1928.
